ASP.net PAYPAL SAMPLE!

I need an asp.net sample using the notify_url with paypal to get the transaction details. The following is code that works fine in calssic asp which paypal posts to. But i can't seem to get it translated to asp.net. Code Start>>>> Dim payment_status, txn_id, custom, mc_gross Dim objHttp, str ' read post from PayPal system and add 'cmd' str = [login to view URL] & "&cmd=_notify-validate" ' post back to PayPal system to validate set objHttp = [login to view URL]("[login to view URL]") ' Use sandbox for testing then change for production. ' "<[login to view URL]>" ' change to: ' "<[login to view URL]>" [login to view URL] "POST", "<[login to view URL]>", false [login to view URL] "Content-type", "application/x-www-form-urlencoded" [login to view URL] str ' assign posted variables to local variables payment_status = [login to view URL]("payment_status") txn_id = [login to view URL]("txn_id") mc_gross = [login to view URL]("mc_gross") custom = [login to view URL]("custom") Code Finish>>>> Thanks T
